HUMIDIFY'ING RADIATOR Filed May 20, 1935 172126 77/ 1607 1" Enoch Z57 /L cuZ/..

Patented Aug. 10, 1937 UNITED STATES PATENT OFFICE 4 Claims.

This invention relates to improvements in humidifying radiators.

The object of the invention is to provide a radiator of the character mentioned having a plurality of groups of radiator sections embodied therein between which humidifiers similar in shape to the radiator sections are interposed, said humidifiers being loosely mounted upon the coup-ling means for the radiator sections and being removable therefrom without disturbing either the radiator sections or their coupling means.-

Another object of the invention is to provide a novel control means whereby the heating fluid for the radiator may be admitted to the several groups of radiator sections, said control means permitting condensation within the radiator sections to drain therefrom automatically when the control means is located in a closed position and when the pressure of the heating fluid is relieved.

Still another object of the invention is to so position the humidifier with respect to a group of radiator sections and an air valve therefor that the air valve will be confined within the humidifier and discharge thereinto.

The invention consists in a radiator as set forth in the following specification and particularly as pointed out in the claims thereof.

Referring to the drawing:

Fig. 1 represents a front elevation of a humidifying radiator embodying my invention, certain portions of said radiator being broken away and illustrated in section.

Fig. 2 is a vertical sectional elevation taken on the line 2-2 of Fig. 1, looking in the direction of the arrows on said line.

Fig. 3 is an enlarged vertical longitudinal sectional view of the valve which controls the admission of heating fluid into the radiator and permits condensation to drain outwardly therethrough.

Fig. 4 is a detail View illustrating a portion of the valve mechanism as viewed in the direction of the arrow Fig. 3.

Fig. 5 is an enlarged detail vertical section through a portion of the valve as taken on the 5 line 5-5 of Fig. 2.

Like numerals refer to like parts throughout the several views of the drawing.

In the drawing, A represents a radiator embodying therein a plurality of groups B, C and D 50 of radiator sections 6 of any desired construction and well known in the art. There may be any number of groups of sections desired and each group may consist of any number of sections 6 desired. The sections 6 of each group of sections 55 may be connected together at the top and bottom thereof in any well-known manner. The groups of sections are connected one to another adjacent to the top thereof and also spaced apart a distance equal to the width of a radiator section 6 by means of suitable coupling members I which 5 are closed at one end thereof at 8 to prevent the heating fluid from passing from one group of sections to another at the top of the radiator. At the bottom of the radiator the groups of sections are connected together and also spaced the required distance apart by means of valves 9.

The valves 9 are of novel construction and constitute manually controlled gravity and pressure actuated means for controlling the passage of the heating fluid from one group of radiator sections to another, and said valves also permit condensation in the groups of sections to drain therefrom automatically when the pressure of the heating fluid is relieved. Each valve 9 embodies therein a casing I0 having a chamber II therein in which a valve member I2 is mounted to contact with an inclined valve seat I3. The Valve member I2 is loosely mounted on a pin I4 which projects into an end of a valve rod I5 and in eifect constitutes a part of said valve rod, and said pin and rod are mounted to rock in unison in bearing portions I6 and Il forming a part of the casing II]. The valve rod I5 has a projection I8 formed thereon which projects into a recessed portion I9 of the valve member I2, said recess being slightly wider than the projection I8, thereby permitting a slight amount of lost motion between said members. A handle 20 is provided for the valve rod I5, said handle preferably being heavier upon one side of said rod than upon the other to overbalance the weight of the valve member I2 when the latter is located in its open position if the rod becomes loose in its stufilng box.

The valve member I2 is raised from the seat I3 to an open position by rotating the valve rod I 5 in a counterclockwise direction as viewed from the front of the radiator, while the movement of said rod in a clockwise direction will permit the valve member I 2 to drop by gravity from its raised or open position to its closed position against the seat I3, and when said valve member is located in this position steam pressure in the chamber II will hold the valve member still more tightly closed. When the steam pressure in the chamber I I is relieved any pressure upon the opposite side of the valve member I2, such as may be caused by condensation accumulating in the radiator sections 6 and rising to a level therein where it will enter a passage 2| of the valve, will cause the valve member to open slightly because of the movement permitted by a space 22 between the lower edge of the projection l8 and the lower edge of the recess i9, thereby permitting said condensation to drain through the valve. A reducing bushing 23 has screw-threaded engagement with the valve casing iii and has a passage 2 extending therethrough which communicates with the valve chamber i i and adjacent radiator section 6. The rotary movement of the valve rod I5 in the casing H3 is limited by a stop screw 25 which projects from said casing into a groove 26 provided in said rod.

A valve 21 for controlling the admission of steam into the group D of radiator sections is constructed and operates in the same manner as are the valves 3, except that the casing thereof is formed as an elbow.

Located between each group of radiator sections 6 above the Valves is a humidifier 28 embodying therein a receptacle 2% for water and a cover 30 therefor. The receptacle 255 is removably supported at St upon the coupling member 1 and is prevented irozn swinging or moving at the bottom thereof by reason of the fact that a recessed portion 32 of the receptacle engages a top portion of the valve 9. The humidifier 28 is constructed to resemble the form and appearance of the radiator sections 6 and present a pleasing appearance between said sections, and the heat transmitted by radiation from the sections 6 will effectively heat the water located in the receptacle 29. Openings are provided in the sides of the cover 36.

Air valves 3 well liIlOWll in the art are provided for each group of radiator sections being attached to the coupling members i and if there is any leakage of moisture from said valves it will drip into the receptacle *9 of the humidifier, and any noise of steam or air escaping from the radiator through the valves 3% is effectively muffled. A flange 35 projects downwardly from the bottom of the receptacle 29 in front of the valve 9 and effectively obscures a large part of said valve from view. I i

It will be evident that any number of groups of radiator sections ii may be utilized as may be required to provide the amount of heat desired. If all of the humidifiers 28 are not required, the waterv may be eliminated therefrom as desired. These humidifiers may be easily and quickly removed from between the groups of radiator sections whenever it is found necessary to remove the water therefrom or clean the receptacle 29 without disturbing the radiator sections or their .coupling means. Condensation within the radiator sections will drain therefrom automatically whenever the steam pressure within the radiator is relieved.

I claim:

1. A radiator comprising groups of radiator sections communicating one with another at the bottom thereof, a coupling connecting adjacent groups of radiator sections together at the top thereof and preventing a heating fluid from passing therebetween, and a humidifier simulating the radiator sections and interposed between groups of radiator sections and loosely suspended upon said coupling, whereby said humidifier may be ,removed from between the groups of sections without loosening the radiator sections and their coupling means.

2. A radiator comprising groups of radiator sections, a coupling connecting adjacent groups of radiator sections together at the top thereof and preventing a heating fluid from passing therebetween, a valve connecting adjacent groups of radiator sections atth'e bottom thereof, and a humidifier interposed between groups of radiator sections and loosely suspended upon said 7 coupling, whereby said humidifier may be removed from between the groups of sections without loosening the coupling means, said humidifier being positioned at the bottom thereof by having engagement with said valve.

3. A radiator comprising groups of radiator sections communicating one with another at the bottom thereof, a coupling connecting adjacent groups of radiator sections together at the top thereof and preventing a heating fluid from passing therebetween, a humidifier interposed between groups of radiator sections and loosely sus- X tached to the coupling and communicating with the radiator sections therethrough and being confined within and discharging into said humidifier.

4. A radiator comprising groups of radiator sections communicating one with another at the whereby said humidifier may be removed from between the groups of sections without loosening the radiator structure.
